How do you define “deify?”
What we are discussing is Calvin's use of the word "deify" and Aquinas' statement that men become "gods."
The two statements are very different.
Calvin is not postulating some neo-Platonic mysticism that blurs the difference between men and God which Aquinas seems to be doing.
When Calvin says "the end of the gospel is, to render us eventually conformable to God, and, if we may so speak, to deify us," he is first laying down the fact that we "conform" to God; we do not "become" God.
Just as Christ justifies the ungodly by imputing HIS righteousness to fallen men, so too does God "deify" some fallen men by imputing to them the effective work of Christ on the cross.
Even Calvin, from the wording of his sentence above ("if we may so speak,") seems to understand the error that might come from taking that comment too literally.
Men do not become gods. Please show me the Scripture that says men becomes gods.
Then quickly inform the LDS that they've had it right all along.
